A nasty leg infection looked likely to have wrecked the 19-year-old national senior champion chances of competing in Glasgow, but she's taken a turn for the better.

Earlier this week the New Zealand medical team were confident Tempero would come right, but the athlete her self was less sure.

After being on antibiotics and undergoing multiple blood tests and injections as well as an MRI scan and two minor surgeries, Tempero wrote on her Instagram page her chances of competing "Aren't very high at the moment".

But an update today from the New Zealand team said they were far more optimistic she would be suited up and taking part when the women's team's event begins Monday night (NZ time).

"She is improving everyday," a New Zealand Olympic Committee spokesperson said."So things are looking positive at this stage."

The intention was still that Tempero would compete, the spokesperson added.

Christchurch-based Wellington gymnast Mackenzie Slee is also under an injury cloud and told Fairfax Media a problem with her big toe might cost her the chance at competing on the beam - one of her strengths.
